The ratio of girls to boys in Charlotte's class is 3:2. This is found by dividing the number of girls by the number of boys to get 21/14 = 3/2.
It is already in its simplest ratio because 17 is a prime number but if it were 7 boys to 21 girls then the ratio would be 1 to 3

B/G = 4/3 so 3B = 4G B+G = 21 Multiply by 3: 3B+3G = 63 But 3B = 4G so 4G+3G = 63 ie 7G = 63 so that G = 9 So B+G=21 means B = 12 3 more boys so B' = 12+3 = 15 1 more girl so G' = 9+1 = 10 So new ratio = B'/G' = 15/10 = 3/2 or 3 to 2
